I am looking for any source info i can find on Video Motion Tracking. Im looking to make a program for computer controlled Pan and Tilt camera. I know there are systems out there that can do this, but I'd like to do my own version.

I need to compare the current frame to the one before and determine an X, Y coordinate system to report how much movement occured. I can then translate this into movement of a servo controlling the pan/tilt. Video handling isnt my strong point in VB. Thanks for any help.
